I've done this bulletin board every year, and the kids (and adults) love it! I send out a letter to the parents asking for random items, and this is what I got this year:) The item to search for changes every day.
Display students birthdays on a board using their photographs. Each student is holding a calendar number of their birthdate. The photo goes under the month heading of the birthday month. The background on this board is wrapping paper. The birthday board accents are available for purchase in Erica Bohrer's TpT store.
